Subject: [PATCH] ipr: Rate limit DMA mapping errors
Date: Mon, 9 May 2011 10:07:40 +1000 [thread overview]
Message-ID: <20110509100740.5eb8f9b5@kryten> (raw)
I noticed a stream of errors from the IPR driver while doing
IOMMU fault injection. Rate limit the errors so we don't clog
up the console and logfiles.
